To all whom it may coa'wcm:

Be it known that 1, JOHN U.

residing at :the city of St. Louisiand State of Missouri,

have invented a new and useful Apparatus for Separating Mechanical Mixtures of Gas, of which the following is a specification.

This invention relates to a new and useful apparatus for separating mechanical mix-- tures of as.

An ob ect of the invention is to provide a suitable apparatus for effecting the machanical separation of volumes of gases in a mechanical mixture, into separate volumes composed of the component gases of the mixture.

With the foregoing objects and additional features and advantages attainable from the present invention portion of the till in view, I have designed an apparatus as shown in the accompanying drawings and herein after disclosed in detail. the accompanying drawings Figure l is a side elevation of an apparatus particularly adapted for practising the improved process of the invention.

Fig. 2 is a similar view with the lower apparatus being shown in section. I

Fig. 3 is a cross section through the apparatus taken substantially on the line 3-3 of i 2 is a cross section taken substanthe line 1 4. of Fig. 2, and

is a cross section taken substann the line 55 oi l f g. 2. In the construction ofrthe'upperatus as illustrated in the drawing l have shown a frame work comprising uprights l a bot tom member2 and an arched top 3. A main operating shaft 4: is supported in the frame work, said shaft being journaled in bearing brackets 5, 6 and 7, respectively. The bracket 6 is bolted to the side members 1 of the frame, substantially intermediate of the top and bottom thereof, to give rigidity to the ame and to maintain the proper alinement of the shaft.

y A receiving chamber A having an annular wall 8 and a cap or closure 10, is supported rigidly within the frame member by integrally formed brackets 9. In order to seal the joint between the cap lOand the wall 8 I provide the upper edge of the wall 8 with an overhanging bead 11, which is adapted to seat within a groove or channel $pecification of Letters Patent.

plate cured to the shaft 4 Patented Dec. d, 1931 l. Serial No. 20,556.

formed in an annular ring 12 which ring is in threaded engagement with the edge of the cap 10. A quantity of oil is placed within the groove or channel in the ring 12 to odect an oil seal of the joint and also to provide a lubricant, so that the cap may turn without friction about the edges of the wall 8.

A chamber B is arranged below the receiving chamber A and comprises an annular side wall 13, a top wall 14 and a bottom wall 15. A sealed joint is provided between lower edge of the chamber A and the upper face of the chamber B. The construction for efiecting the seal comprises a trough formed on the upper wall of the chamber by an annular vertical flange 16 and an annular ring 17 in threaded. engagement with,a second ring 18 carried by the top 14 of the chamber B. flange 19 formed at the lower edge of the wall '8 extends into said trough. It will be understood that a quantity of oil is provided in said trough effectively to constitute an oil seal as well as to provide a lubricant preventing friction as the chamber B is rotated.

At the center of the chamber Bis a hub member 20 through which the shaft 4 extends. The hub member is releasably seby a set screw 21 or other suitable binding device. A series of blades or vanes 22 connected with the hub member and extending radially therefrom are provided for the purpose of agitating the contents of the chamber. In the top wall 14 of the chamber B and encircling the upper edge of the hub 20 is a series of openings 23, providing passage-ways between the chambers A and B.

The lower wall 15 of the chamber B is in the form of a circular plate in which is formed a plurality of concentric circular series of openings 24:, 25 and 26, respectively.- The openings are arranged in series on parallel spaced circles and are adapted to provide ports or outlets for the separated gases in difi'erent vertical zones, as fully explained hereinafter.

Below the chamber B is arranged a series of chambers C, D and E, respectively. The chambers C, D and E are located within a common annular side wall 27 which is supported rigidly in the frame by brackets 28, and are disposed, respectively, betweena top wall 29, partition walls 30 and 31 and will be more llll.

Separate sages leading to the respective o each of the passages opening centiv respectively to the series of on t ports 24, 25 and; 26. The independent passages }ust Y mentioned are separated by partition walls Thewall 33 is a lower edge of a tongue 33, which in a groove formed be- .33, 34 and 35, respectively.

which is curved to form 29 and an annular rmg 3'1 carried by the upper face of the wall 29 with which it has threadedengagement. The wall 33 is l.- shapcd in cross-section and has threaded engagement at its upper end with the wall 15 and has 'one leg thereof extending downtengue which is adapted to seat in a groove c substantially the same structure as that 1s described. The Wall 34 extends downwardiy below the edge of the depending portion of the wall 32 and is provided with a tongue at its lower edge adapted to seat in a groove of ;the same constructionv as that above described. The construction of the joints between the walls 32, 33 and-34 and the respective walls forming thechambers C, D, and E, that has just been described is such that a seal is provided between the respective partition walls which turn with and may be considered as a part of the chamber B and the stationary chambers C, D andE. it will also be understood that oil is provided in the grooves that have, been described, for the purpose of efiecting the sealing of the joints and also of lubricating the parts, permitting the same degree of fricto operate with a minimum tion. In order to effectively seal the opening in the center of the bottom wall 32, I provide a cap member 38 releasably secured to the shaft 4 which cap has inclined edges adapted to operate in oil containing troughs formed between the inclined edges of the wall 32 surrounding the opening an a member 39 in threaded engagement with the threaded edges of said opening.

A number of exhausters 40, 41 and 42 are mounted in the upper part of the frame. The rotors of the exhausters are connected to and actuated by the shaft 4. The exhausters are" connected respectively with the chambers G, D and E, by conduits or pipes 43, 44 and 45.

A conduit 46 connected into the chamber A and leading from the container for the mixed gases is provided, and constitutes a supply conduit whereby the gases to be separated may be introduced into the -receiving chamber.

Service conduits 47, 48 and 49 leading from the exhausters provide means for conducting the separated gases to storage containers or other receivers for use.

pass from the bottom of the chamber B into .5 belt pulley 5G is mounted on the shaft whereby power from any suitable source may be provided for driving the shaft and actuating the apparatus.

From the foregoing it will. be understood that the process of separation of mechanical gases is practised on the apparatus as fol lows.

The mixed gases are drawn into the chamher A from the conduit 46, from whence they pass into the chamber B.

The shaft 4 is rotated at a high speed thereby revolving the vanes or blades 22 and the chamber B at a high velocity. The volume of mixed gas introduced into the chamber B is subjected to the whirling action of the blades 22 and chamber B thereby, through centrifugal action, causing the heavier gas to move to the outer zone of the chamber, the lighter gas remaining in a zone adjacent to the axis of the revolving chamber, with the imperfectly separated strata being in the intermediate zone. From the several zones the now separated gases the several recelving chambers C, D and E,

respectively, from whence they are drawn by the exhausters through the conduits 43, 44 and 45 and discharged into the service passages 47, 48 and-49, to be conducted to 9r separate receiving chambers.
